fix(firefox): copy the wallpaper, Firefox won't follow the link

The darknix.png symlink out of the profile left the new tab blank, even
after a restart: Firefox's sandbox does not follow it. udt-accent now
copies the wallpaper over the slot on every change instead, removing any
leftover link first so the copy cannot write through it into the
wallpaper. install.sh no longer makes the link.
